摘　　要：目的:分析彩色多谱勒超声诊断产后胎盘植入效果及声像图特征。方法:收集2019年2月-2020年2月在本院分娩的产后胎盘植入产妇30例临床资料,均行彩色多普勒及核磁共振(MRI)检查,依据产后胎盘组织病理结果确诊,比较两种检查方法产后胎盘植入的诊断结果并分析声像图特点。结果:彩色多普勒诊断产后胎盘植入的敏感性(91.2%)高于MRI检查(82.5%)(P<0.05),而诊断准确性、特异性、阴性预测值、阳性预测值、假阳性率、假阴性率、精确比、诊断指数以及Kappa值等与MRI检查无差异(P>0.05)。经彩色多普勒检查的30例中,有1例误诊为胎盘粘连。结论:彩色多普勒用于产后胎盘植入诊断价值与MRI检查相似,可为临床处理胎盘植入提供可靠依据。Objective: To study the effect of color Doppler ultrasonography for diagnosing postpartum placenta increta, and to analyze its sonographic features. Methods: The clinical data of 30 women with diagnosed postpartum placenta implantation from February 2019 to February 2020 were collected. All these women had accepted color Doppler and magnetic resonance imaging(MRI) examination before delivery. Based on the postpartum placental tissue pathological results, the effect of diagnostical placenta increta was compared between color Doppler and MRI, and the sonographic features by color Doppler and MRI were analyzed. Results: The sensitivity of color Doppler for diagnosing placenta increta was 91.2%, which was significant higher than that(82.5%) of MRI(P<0.05), but the diagnostic accuracy, the specificity, the negative predictive value, the positive predictive value, the false positive rate, the false negative rate, the exact ratio, the diagnostic index, and Kappa value had no significant different between color Doppler and MRI(P>0.05). In 30 women who had examined by color Doppler, there was 1 case misdiagnosed as placental adhesion. Conclusion: The value of color Doppler ultrasound for diagnosing placenta increta is similar to that of MRI, which can provide reliable evidence for clinical treatment of placenta increta.
